Wide screen telephones could soon be the access point for the useful stops on the superhighway in British homes, following US marketing trials of Northern Telecom Ltd’s ADSI phone system. The Analogue Display Services Interface phone system was designed last year and is being trialled by the Bank of Boston with its New England customers, and in the Canadian town of St John, New Brunswick. It comprises a standard telephone set with a removable LCD screen-and-button module varying in size and functions at varying end-user prices. The phone is expected to start at around ú200. On-line banking is the most common use in these trials but services open to Analogue Display customers include ordering tickets and listening to music before buying it. The equipment is awaiting acceptance from UK telecommunications companies, believed to be awaiting reports from North America before going ahead with other experiments.
